What is android-background-work?

A Kotlin reference for running Android work in the background or asynchronously. It covers tools such as WorkManager, services, alarms, broadcasts, job scheduling, and Kotlin coroutines, which let apps perform tasks outside the main screen interaction.

It helps build background jobs, foreground or bound services, scheduled alarms, broadcast receivers, coroutine-based tasks, and related tests in Android apps.

It gives developers a reference for choosing and implementing Android background tasks. It also covers system limits such as Doze and ways to test this work.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00109	$0.01469
Opus 5	$0.00055	$0.00734
Sonnet 5	$0.00022	$0.00294
Haiku 4.5	$0.00011	$0.00147

Measured 5d ago against content hash 68ae157d6455, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-05, from the pricing page.

Security

Grade A, and why

android-background-work scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What ships with it

60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
